Visualization of dynamic connectivity in high electrode-density EEG Conference Paper uri icon

abstract

  • A visualization methodology for the analysis of dynamic synchronization in electroencephalograph^ signals is presented here. The proposed method is based on a seeded region-growing segmentation of the time-frequency space in terms of spatial connectivity patterns, a process that can be fully automated by cleverly choosing the seeds. A Bayesian regularization technique is applied to further improve the results. Finally, preliminary results from the analysis of a high electrode-density dataset with 120 channels are shown. © Springer-Verlag Berlin Heidelberg 2008.
